Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing apparatuses for producing cushion products from continuous paper strips face challenges in achieving high cushion quality and processing velocity while avoiding paper jams and ensuring eco-friendliness.
Innovation Solution
An apparatus comprising a tube-like preforming station for compressing and folding the paper strip, a deformation station with embossing rollers to form crumple hollow spaces, and a lifting unit to elevate the central area of the paper strip, enhancing the deformation process and reducing tensile stress, is used to produce cushion products from recycled paper strips.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the paper strip is processed at high velocity to increase productivity, then the production efficiency is improved, but the risk of paper jam and loss of cushion quality increases
Solution Approach 1:
The lifting unit is positioned upstream of the deformation station to preemptively lift the central area of the paper strip before it enters the deformation zone. This preliminary action prevents sagging and reduces tensile stress during high-velocity processing, thereby eliminating paper jam risks while maintaining high productivity
Solution Approach 2:
The lifting unit changes the vertical position parameter of the paper strip's central area, elevating it to an optimal height before deformation. This parameter adjustment ensures proper paper strip positioning during high-speed operation, preventing jams and maintaining cushion quality
2Device complexity
If the central area of the paper strip is not lifted, then the device complexity is reduced, but the cushion product quality and damping ability deteriorate
Solution Approach 1:
The lifting unit applies localized action only to the central area of the paper strip, leaving the rest of the strip unchanged. This targeted approach improves cushion quality and damping ability without requiring complex system-wide modifications, maintaining relatively simple device structure
Solution Approach 2:
The lifting unit acts as an intermediary component between the paper strip supply and the deformation station. It mediates the paper strip's position and tension, ensuring optimal conditions for deformation and high-quality cushion production without overwhelming system complexity
3Manufacturing precision
If the paper strip width is increased to provide sufficient material for cushion formation, then the cushion quality is improved, but the risk of sagging and paper jam increases
Solution Approach 1:
The lifting unit provides an upward lifting force that counteracts the gravitational sagging of the wide paper strip. By compensating for the weight-induced sagging, the system can process wider paper strips for better cushion quality without increasing the risk of paper jam

Implementation Method 1
The lifting unit is designed to lift the central area of the paper strip perpendicularly to the feed direction of the paper strip and transverse to the transverse direction of the paper strip
Implementation Method 2
The deformation station (13) comprises two embossing rollers (31, 33) engaging into each other in the deformation area (35) in order to form the paper strip (5) to a cushion product (3)
Implementation Method 3

AI summary
An apparatus for the production of a cushion product from a single or multi-layer continuous paper strip includes a chute-like preforming station for the compression of a paper strip in the transverse direction and a deformation station following the preforming station in the feed direction of the paper strip having two embossing rollers engaging into each other in a deformation area in order to form the paper strip to a cushion product with at least one crumple hollow space extending in the longitudinal direction. The preforming station has a lifting unit and is positioned upstream in the feed direction of the embossing rollers for lifting a central area of the paper strip.
